Adding XCFramework creates swift support folder missing error.
Hello, In my IOS app, I have been working on implementing a third-party library's xcframework into my app. (They don't provide spm or cocoapods). However, whenever I import the XCFramework into my app, the build is successful, but when uploading to App Store Connect, I receive an email with an error stating the Swift Support folder is missing. This app was made using SwiftUI. I have a sample project linked below. Other apps also use this framework, so I'm not sure where I'm going wrong. Project

Which extension use
Hi, I want to block incoming calls using my backend server, like the unwantend sms using message filter extension. I saw that Call Directory Extension can block numbers, but you need update the list, is not in real time. I was reading the Live Caller ID Look up extension documentation, and it seems that with this extension is possible send the number to backend and retrieve a value to know if the call should be block or not. Am I right? Or is not possible this feature with this extension? Thanks!

Question with Message Filter Extension
Hi. I created a Message Filter Extension target to filter spam sms messages, deferring the request to my backend. The extension makes the call and send this payload: POST /server-endpoint HTTP/1.1 Accept: */* Content-Type: application/json; charset=utf-8 Content-Length: 148 { "_version": 1, "query": { "sender": "14085550001", "message": { "text": "This is a message" } }, "app": { "version": "1.1" } } My question is, is possible modify this payload to send the "receiver" number (is possible get the receiver number in this extension?), or use an identifier, to let my backend know which user number the filter was applied to. I think is impossible because the extension makes the call and create the payload, and I don't see anything in docs to add other prop, but there's other way to know the "receiver" number of the sms? Thanks:)

Can't install any apps on my new iPhone 16 Pro with iOS 18 from XCode
Error message: Previous preparation error: The developer disk image could not be mounted on this device.; Error mounting image: 0xe800010f (kAMDMobileImageMounterPersonalizedBundleMissingVariantError: The bundle image is missing the requested variant for this device.) I had no issues previously with my iPhone 13 Pro running iOS 18 and my XCode 15. Now, after switching to the iPhone 16 Pro, it won't work. I've tried restarting my phone several times, quitting XCode, removing and readding developer mode—nothing quite works.

Can't archive app due to icon error.
I'm developing a companion watch app for an already existing iOS app, and everything seems to be working fine compiling it for the simulator, however when I try to archive it so I can make it available on TestFlight XCode throws the error "The stickers icon set or app icon set named "AppIcon" did not have any applicable content" even though the app icon is in the assets. The icon works and appears fine under the Simulator but I can't seem to archive it, even after renaming it to something else.

Apple developer taking weeks
I enrolled to the apple developer account more than one week ago. Nothing! After 3 or 4 emails to support I received an email with steps I should perform from the iPhone app. I did so, my money was charged and ... nothing. My enrollment has been withdrawn no activation nothing. I made another request (although I am not sure that it is ok). Can somebody help me?

Analyzing crash report
Hello, I'm doing an update to my app already IN the app store. The app is built using .Net Maui targeting iOS, Windows and Android. All works fine in debug and in release on Android and Windows. However, the app launches on my iOS devices and crashes immediately. I really have no idea what the crash report on the device is telling me. Attached is the .ips file if anyone can at least point me in the right direction... Thanks MyApp-2025-03-01-202630.ips

Xcode 16 „forgetting“ package in subfolder to root package
Xcode 16 seems to „forget“ a swift package within a subfolder of a root package after restart or shut-down. I have the following project structure, which also resembles the directory structure on disc: MyPackage - Package.swift - README.md - Sources - MyPackage - Tests - MyPackageTests - Tools - MyGenerator // <- after restart this folder is not visible in the Xcode project navigator - Package.swift - Sources - main.swift - Tests MyGenerator is a standalone package which is used during development of MyPackage to generate source code files for MyPackage based on text file input. Essentially an executable target script which I can run within its folder with: swift run MyGenerator someInputFile.txt MyPackage does NOT use MyGenerator as a dependency, nor do I want this tool listed as a dependency in MyPackage Package.swift file. Yet MyGenerator is part of the same Git repo, as it documents the changes to the tool on how to generate source code for MyPackage. Both packages are developed in tandem. MyGenerator itself defines dependencies in its Package.swift file, which are unrelated to the functionality of MyPackage. After restart of Xcode or even just a longer shut-down period the MyGenerator subfolder is not visible in the Xcode project navigator, the /Tools folder is empty. I have to manually add the sub package via Add files to "MyPackage" -> Move files to destination every time. How can I solve that Xcode remembers the sub package unter /Tools? Edit: I am using Xcode 16.2

Understanding Mach-O Symbols
This posts collects together a bunch of information about the symbols found in a Mach-O file. It assumes the terminology defined in An Apple Library Primer. If you’re unfamiliar with a term used here, look there for the definition. If you have any questions or comments about this, start a new thread in the Developer Tools & Services > General topic area and tag it with Linker. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Understanding Mach-O Symbols Every Mach-O file has a symbol table. This symbol table has many different uses: During development, it’s written by the compiler. And both read and written by the linker. And various other tools. During execution, it’s read by the dynamic linker. And also by various APIs, most notably dlsym. The symbol table is an array of entries. The format of each entry is very simple, but they have been used and combined in various creative ways to achieve a wide range of goals. For example: In a Mach-O object file, there’s an entry for each symbol exported to the linker. In a Mach-O image, there’s an entry for each symbol exported to the dynamic linker. And an entry for each symbol imported from dynamic libraries. Some entries hold information used by the debugger. See Debug Symbols, below. Examining the Symbol Table There are numerous tools to view and manipulate the symbol table, including nm, dyld_info, symbols, strip, and nmedit. Each of these has its own man page. A good place to start is nm: % nm Products/Debug/TestSymTab U ___stdoutp 0000000100000000 T __mh_execute_header U _fprintf U _getpid 0000000100003f44 T _main 0000000100008000 d _tDefault 0000000100003ecc T _test 0000000100003f04 t _testHelper Note In the examples in this post, TestSymTab is a Mach-O executable that’s formed by linking two Mach-O object files, main.o and TestCore.o. There are three columns here, and the second is the most important. It’s a single letter indicating the type of the entry. For example, T is a code symbol (in Unix parlance, code is in the text segment), D is a data symbol, and so on. An uppercase letter indicates that the symbol is visible to the linker; a lowercase letter indicates that it’s internal. An undefined (U) symbol has two potential meanings: In a Mach-O image, the symbol is typically imported from a specific dynamic library. The dynamic linker connects this import to the corresponding exported symbol of the dynamic library at load time. In a Mach-O object file, the symbol is undefined. In most cases the linker will try to resolve this symbol at link time. Note The above is a bit vague because there are numerous edge cases in how the system handles undefined symbols. For more on this, see Undefined Symbols, below. The first column in the nm output is the address associated with the entry, or blank if an address is not relevant for this type of entry. For a Mach-O image, this address is based on the load address, so the actual address at runtime is offset by the slide. See An Apple Library Primer for more about those concepts. The third column is the name for this entry. These names have a leading underscore because that’s the standard name mangling for C. See An Apple Library Primer for more about name mangling. The nm tool has a lot of formatting options. The ones I use the most are: -m — This prints more information about each symbol table entry. For example, if a symbol is imported from a dynamic library, this prints the library name. For a concrete example, see A Deeper Examination below. -a — This prints all the entries, including debug symbols. We’ll come back to that in the Debug Symbols section, below. -p — By default nm sorts entries by their address. This disables that sort, causing nm to print the entries in the order in which they occur in the symbol table. -x — This outputs entries in a raw format, which is great when you’re trying to understand what’s really going on. See Raw Symbol Information, below, for an example of this. A Deeper Examination To get more information about each symbol table, run nm with the -m option: % nm -m Products/Debug/TestSymTab (undefined) external ___stdoutp (from libSystem) 0000000100000000 (__TEXT,__text) [referenced dynamically] external __mh_execute_header (undefined) external _fprintf (from libSystem) (undefined) external _getpid (from libSystem) 0000000100003f44 (__TEXT,__text) external _main 0000000100008000 (__DATA,__data) non-external _tDefault 0000000100003ecc (__TEXT,__text) external _test 0000000100003f04 (__TEXT,__text) non-external _testHelper This contains a world of extra information about each entry. For example: You no longer have to remember cryptic single letter codes. Instead of U, you get undefined. If the symbol is imported from a dynamic library, it gives the name of that dynamic library. Here we see that _fprintf is imported from the libSystem library. It surfaces additional, more obscure information. For example, the referenced dynamically flag is a flag used by the linker to indicate that a symbol is… well… referenced dynamically, and thus shouldn’t be dead stripped. Undefined Symbols Mach-O’s handling of undefined symbols is quite complex. To start, you need to draw a distinction between the linker (aka the static linker) and the dynamic linker. Undefined Symbols at Link Time The linker takes a set of files as its input and produces a single file as its output. The input files can be Mach-O images or dynamic libraries [1]. The output file is typically a Mach-O image [2]. The goal of the linker is to merge the object files, resolving any undefined symbols used by those object files, and create the Mach-O image. There are two standard ways to resolve an undefined symbol: To a symbol exported by another Mach-O object file To a symbol exported by a dynamic library In the first case, the undefined symbol disappears in a puff of linker magic. In the second case, it records that the generated Mach-O image depends on that dynamic library [3] and adds a symbol table entry for that specific symbol. That entry is also shown as undefined, but it now indicates the library that the symbol is being imported from. This is the core of the two-level namespace. A Mach-O image that imports a symbol records both the symbol name and the library that exports the symbol. The above describes the standard ways used by the linker to resolve symbols. However, there are many subtleties here. The most radical is the flat namespace. That’s out of scope for this post, because it’s a really bad option for the vast majority of products. However, if you’re curious, the ld man page has some info about how symbol resolution works in that case. A more interesting case is the -undefined dynamic_lookup option. This represents a halfway house between the two-level namespace and the flat namespace. When you link a Mach-O image with this option, the linker resolves any undefined symbols by adding a dynamic lookup undefined entry to the symbol table. At load time, the dynamic linker attempts to resolve that symbol by searching all loaded images. This is useful if your software works on other Unix-y platforms, where a flat namespace is the norm. It can simplify your build system without going all the way to the flat namespace. Of course, if you use this facility and there are multiple libraries that export that symbol, you might be in for a surprise! [1] These days it’s more common for the build system to pass a stub library (.tbd) to the linker. The effect is much the same as passing in a dynamic library. In this discussion I’m sticking with the old mechanism, so just assume that I mean dynamic library or stub library. If you’re unfamiliar with the concept of a stub library, see An Apple Library Primer. [2] The linker can also merge the object files together into a single object file, but that’s relatively uncommon operation. For more on that, see the discussion of the -r option in the ld man page. [3] It adds an LC_LOAD_DYLIB load command with the install name from the dynamic library. See Dynamic Library Identification for more on that. Undefined Symbols at Load Time When you load a Mach-O image the dynamic linker is responsible for finding all the libraries it depends on, loading them, and connecting your imports to their exports. In the typical case the undefined entry in your symbol table records the symbol name and the library that exports the symbol. This allows the dynamic linker to quickly and unambiguously find the correct symbol. However, if the entry is marked as dynamic lookup [1], the dynamic linker will search all loaded images for the symbol and connect your library to the first one it finds. If the dynamic linker is unable to find a symbol, its default behaviour is to fail the load of the Mach-O image. This changes if the symbol is a weak reference. In that case, the dynamic linking continues to load the image but sets the address of the symbol to NULL. See Weak vs Weak vs Weak, below, for more about this. [1] In this case nm shows the library name as dynamically looked up. Weak vs Weak vs Weak Mach-O supports two different types of weak symbols: Weak references (aka weak imports) Weak definitions IMPORTANT If you use the term weak without qualification, the meaning depends on your audience. App developers tend to assume that you mean a weak reference whereas folks with a C++ background tend to assume that you mean a weak definition. It’s best to be specific. Weak References Weak references support the availability mechanism on Apple platforms. Most developers build their apps with the latest SDK and specify a deployment target, that is, the oldest OS version on which their app runs. Within the SDK, each declaration is annotated with the OS version that introduced that symbol [1]. If the app uses a symbol introduced later than its deployment target, the compiler flags that import as a weak reference. The app is then responsible for not using the symbol if it’s run on an OS release where it’s not available. For example, consider this snippet: #include <xpc/xpc.h> void testWeakReference(void) { printf("%p\n", xpc_listener_set_peer_code_signing_requirement); } The xpc_listener_set_peer_code_signing_requirement function is declared like so: API_AVAILABLE(macos(14.4)) … int xpc_listener_set_peer_code_signing_requirement(…); The API_AVAILABLE macro indicates that the symbol was introduced in macOS 14.4. If you build this code with the deployment target set to macOS 13, the symbol is marked as a weak reference: % nm -m Products/Debug/TestWeakRefC … (undefined) weak external _xpc_listener_set_peer_code_signing_requirement (from libSystem) If you run the above program on macOS 13, it’ll print NULL (actually 0x0). Without support for weak references, the dynamic linker on macOS 13 would fail to load the program because the _xpc_listener_set_peer_code_signing_requirement symbol is unavailable. [1] In practice most of the SDK’s declarations don’t have availability annotations because they were introduced before the minimum deployment target supported by that SDK. Weak definitions Weak references are about imports. Weak definitions are about exports. A weak definition allows you to export a symbol from multiple images. The dynamic linker coalesces these symbol definitions. Specifically: The first time it loads a library with a given weak definition, the dynamic linker makes it the primary. It registers that definition such that all references to the symbol resolve to it. This registration occurs in a namespace dedicated to weak definitions. That namespace is flat. Any subsequent definitions of that symbol are ignored. Weak definitions are weird, but they’re necessary to support C++’s One Definition Rule in a dynamically linked environment. IMPORTANT Weak definitions are not just weird, but also inefficient. Avoid them where you can. To flush out any unexpected weak definitions, pass the -warn_weak_exports option to the static linker. The easiest way to create a weak definition is with the weak attribute: __attribute__((weak)) void testWeakDefinition(void) { } IMPORTANT The C++ compiler can generate weak definitions without weak ever appearing in your code. This shows up in nm like so: % nm -m Products/Debug/TestWeakDefC … 0000000100003f40 (__TEXT,__text) weak external _testWeakDefinition … The output is quite subtle. A symbol flagged as weak external is either a weak reference or a weak definition depending on whether it’s undefined or not. For clarity, use dyld_info instead: % dyld_info -imports -exports Products/Debug/TestWeakRefC Products/Debug/TestWeakDefC [arm64]: … -imports: … 0x0001 _xpc_listener_set_peer_code_signing_requirement [weak-import] (from libSystem) % dyld_info -imports -exports Products/Debug/TestWeakDefC Products/Debug/TestWeakDefC [arm64]: -exports: offset symbol … 0x00003F40 _testWeakDefinition [weak-def] … … Here, weak-import indicates a weak reference and weak-def a weak definition. Weak Library There’s one final confusing use of the term weak, that is, weak libraries. A Mach-O image includes a list of imported libraries and a list of symbols along with the libraries they’re imported from. If an image references a library that’s not present, the dynamic linker will fail to load the library even if all the symbols it references in that library are weak references. To get around this you need to mark the library itself as weak. If you’re using Xcode it will often do this for your automatically. If it doesn’t, mark the library as optional in the Link Binary with Libraries build phase. Use otool to see whether a library is required or optional. For example, this shows an optional library: % otool -L Products/Debug/TestWeakRefC Products/Debug/TestWeakRefC: /usr/lib/libEndpointSecurity.dylib (… 511.60.5, weak) … In the non-optional case, there’s no weak indicator: % otool -L Products/Debug/TestWeakRefC Products/Debug/TestWeakRefC: /usr/lib/libEndpointSecurity.dylib (… 511.60.5) … Debug Symbols or Why the DWARF still stabs. (-: Historically, all debug information was stored in symbol table entries, using a format knows as stabs. This format is now obsolete, having been largely replaced by DWARF. However, stabs symbols are still used for some specific roles. Note See <mach-o/stab.h> and the stab man page for more about stabs on Apple platforms. See stabs and DWARF for general information about these formats. In DWARF, debug symbols aren’t stored in the symbol table. Rather, debug information is stored in various __DWARF sections. For example: % otool -l Intermediates.noindex/TestSymTab.build/Debug/TestSymTab.build/Objects-normal/arm64/TestCore.o | grep __DWARF -B 1 sectname __debug_abbrev segname __DWARF … The compiler inserts this debug information into the Mach-O object file that it creates. Eventually this Mach-O object file is linked into a Mach-O image. At that point one of two things happens, depending on the Debug Information Format build setting. During day-to-day development, set Debug Information Format to DWARF. When the linker creates a Mach-O image from a bunch of Mach-O object files, it doesn’t do anything with the DWARF information in those objects. Rather, it records references to the source objects files into the final image. This is super quick. When you debug that Mach-O image, the debugger finds those references and uses them to locate the DWARF information in the original Mach-O object files. Each reference is stored in a stabs OSO symbol table entry. To see them, run nm with the -a option: % nm -a Products/Debug/TestSymTab … 0000000000000000 - 00 0001 OSO …/Intermediates.noindex/TestSymTab.build/Debug/TestSymTab.build/Objects-normal/arm64/TestCore.o 0000000000000000 - 00 0001 OSO …/Intermediates.noindex/TestSymTab.build/Debug/TestSymTab.build/Objects-normal/arm64/main.o … Given the above, the debugger knows to look for DWARF information in TestCore.o and main.o. And notably, the executable does not contain any DWARF sections: % otool -l Products/Debug/TestSymTab | grep __DWARF -B 1 % When you build your app for distribution, set Debug Information Format to DWARF with dSYM File. The executable now contains no DWARF information: % otool -l Products/Release/TestSymTab | grep __DWARF -B 1 % Xcode runs dsymutil tool to collect the DWARF information, organise it, and export a .dSYM file. This is actually a document package, within which is a Mach-O dSYM companion file: % find Products/Release/TestSymTab.dSYM Products/Release/TestSymTab.dSYM Products/Release/TestSymTab.dSYM/Contents … Products/Release/TestSymTab.dSYM/Contents/Resources/DWARF Products/Release/TestSymTab.dSYM/Contents/Resources/DWARF/TestSymTab … % file Products/Release/TestSymTab.dSYM/Contents/Resources/DWARF/TestSymTab Products/Release/TestSymTab.dSYM/Contents/Resources/DWARF/TestSymTab: Mach-O 64-bit dSYM companion file arm64 That file contains a copy of the the DWARF information from all the original Mach-O object files, optimised for use by the debugger: % otool -l Products/Release/TestSymTab.dSYM/Contents/Resources/DWARF/TestSymTab | grep __DWARF -B 1 … sectname __debug_line segname __DWARF … Raw Symbol Information As described above, each Mach-O file has a symbol table that’s an array of symbol table entries. The structure of each entry is defined by the declarations in <mach-o/nlist.h> [1]. While there is an nlist man page, the best documentation for this format is the the comments in the header itself. Note The terms nlist stands for name list and dates back to truly ancient versions of Unix. Each entry is represented by an nlist_64 structure (nlist for 32-bit Mach-O files) with five fields: n_strx ‘points’ to the string for this entry. n_type encodes the entry type. This is actually split up into four subfields, as discussed below. n_sect is the section number for this entry. n_desc is additional information. n_value is the address of the symbol. The four fields within n_type are N_STAB (3 bits), N_PEXT (1 bit), N_TYPE (3 bits), and N_EXT (1 bit). To see these raw values, run nm with the -x option: % nm -a -x Products/Debug/TestSymTab … 0000000000000000 01 00 0300 00000036 _getpid 0000000100003f44 24 01 0000 00000016 _main 0000000100003f44 0f 01 0000 00000016 _main … This prints a column for n_value, n_type, n_sect, n_desc, and n_strx. The last column is the string you get when you follow the ‘pointer’ in n_strx. The mechanism used to encode all the necessary info into these fields is both complex and arcane. For the details, see the comments in <mach-o/nlist.h> and <mach-o/stab.h>. However, just to give you a taste: The entry for getpid has an n_type field with just the N_EXT flag set, indicating that this is an external symbol. The n_sect field is 0, indicating a text symbol. And n_desc is 0x0300, with the top byte indicating that the symbol is imported from the third dynamic library. The first entry for _main has an n_type field set to N_FUN, indicating a stabs function symbol. The n_desc field is the line number, that is, line 22. The second entry for _main has an n_type field with N_TYPE set to N_SECT and the N_EXT flag set, indicating a symbol exported from a section. In this case the section number is 1, that is, the text section. [1] There is also an <nlist.h> header that defines an API that returns the symbol table. The difference between <nlist.h> and <mach-o/nlist.h> is that the former defines an API whereas the latter defines the Mach-O on-disk format. Don’t include both; that won’t end well!

devicectl copy directory recursively
I can use devicectl to copy single files from a device fine using: xcrun devicectl --verbose device copy from --user mobile --domain-identifier <BUNDLE_ID> --domain-type appDataContainer --device <DEVICE_ID> --source Documents/Screenshots/0001.png --destination Screeshots/0001.png but when there are many files this can get pretty slow. Is there a way of recursively copying an entire directory? I've tried this: xcrun devicectl --verbose device copy from --user mobile --domain-identifier <BUNDLE_ID> --domain-type appDataContainer --device <DEVICE_ID> --source Documents/Screenshots --destination Screeshots but nothing is transferred and it times out eventually with the error: ERROR: The specified file could not be transferred. (com.apple.dt.CoreDeviceError error 7000 (0x1B58)) ERROR: The operation couldn’t be completed. The file service client failed to read data from the network socket because we timed out when waiting for data to become available. (NSPOSIXErrorDomain error 60 (0x3C)) NSLocalizedFailureReason = The file service client failed to read data from the network socket because we timed out when waiting for data to become available. Xcode itself can do it with the "download container..." option, but I'd like to be able to automate it.

Issue with Apple Developer Enrollment – Stuck in Pending State
Hello, I've noticed that many people on the forum are experiencing issues enrolling in the Apple Developer Program. I’m facing the same problem—I can't complete my enrollment using my MacBook Pro. When I try to enroll through the Apple Developer app, I get an error saying, "Enrollment through the Apple Developer app is not available for this Apple ID." So, I tried using Safari instead. I submitted all my personal information and credit card details and initiated the order. However, no transaction was processed from my bank account, and I received an email stating that I would be notified when my order and items are ready. When I check the Apple Developer portal, my enrollment status is Pending, and I see a message prompting me to complete the purchase, as if I need to make a new payment. I don’t understand why Apple makes it so complicated just to subscribe to the Developer Program. Why can’t I use my MacBook Pro for enrollment? Why does the Developer portal ask me to complete the purchase even though I already submitted my payment details? Why is the process so confusing? Any help or clarification would be greatly appreciated. Thanks!

Fresh Project Using Insecure APIs (_sscanf, _strlen, _fopen, malloc) in Binary
Hello Apple Developer Community, I recently created a fresh project with: No dependencies No additional written code After generating the iOS build, I navigated to the build folder: cd build/ios/iphoneos/Runner.app Then, I ran the following commands to inspect the binary: otool -Iv Runner | grep -w _strlen otool -Iv Runner | grep -w _malloc Surprisingly, I received positive results, meaning these functions are present in the binary. My Questions: Why is a fresh Flutter project (with no extra dependencies) including these APIs in the binary?

Adding ‘Test diamonds’ to Xcode with a macro
I'm currently writing a macro which outputs Swift Testing code: // Macro code ... @MainActor @SnapshotSuite struct MySuite { func makeView() -&gt; some View { Text("a view") } } which expands to... // Expanded macro code ... @MainActor @Suite struct _GeneratedSnapshotSuite { @MainActor @Test(.tags(.snapshots)) func assertSnapshotMakeView() async throws { let generator = SnapshotGenerator( testName: "makeView", traits: [ .theme(.all), .sizes(devices: .iPhoneX, fitting: .widthAndHeight), .record(false), ], configuration: .none, makeValue: { MySuite().makeView() }, fileID: #fileID, filePath: #filePath, line: 108, column: 5 ) await __assertSnapshot(generator: generator) } } In short, this macro creates snapshot tests from a function. This all works but I'm finding a couple of limitations, potentially with how Macros are expanded in Swift. Xcode diamonds are not visible The snapshots tag isn't discovered There are a couple of things worth noting though: The suites and tests are discovered in Xcode's Test Navigator each time Xcode runs tests (cmd + u) - although they need to rerun to be updated. I manually add a @Suite in my code as well as my @SnapshotSuite to all of the suites. (The tags never seem to be available though) Couple of questions on this: Is this a known issue? Are there any workarounds? I do wonder if there's a workaround for showing the diamonds with XCTest APIs such as: https://github.com/swiftlang/swift-corelibs-xctest/tree/main https://developer.apple.com/documentation/xctest

Not Sandbox App, Working on SMAppService as root
I am currently developing a No-Sandbox application. What I want to achieve is to use AuthorizationCopyRights in a No-Sandbox application to elevate to root, then register SMAppService.daemon after elevation, and finally call the registered daemon from within the No-Sandbox application. Implementation Details Here is the Plist that I am registering with SMAppService: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.example.agent</string> <key>BundleProgram</key> <string>/usr/local/bin/test</string> <key>ProgramArguments</key> <array> <string>/usr/local/bin/test</string> <string>login</string> </array> <key>RunAtLoad</key> <true/> </dict> </plist> Code that successfully performs privilege escalation (a helper tool popup appears) private func registerSMAppServiceDaemon() -> Bool { let service = SMAppService.daemon(plistName: "com.example.plist") do { try service.register() print("Successfully registered \(service)") return true } catch { print("Unable to register \(error)") return false } } private func levelUpRoot() -> Bool { var authRef: AuthorizationRef? let status = AuthorizationCreate(nil, nil, [], &authRef) if status != errAuthorizationSuccess { return false } let rightName = kSMRightBlessPrivilegedHelper return rightName.withCString { cStringName -> Bool in var authItem = AuthorizationItem( name: cStringName, valueLength: 0, value: nil, flags: 0 ) return withUnsafeMutablePointer(to: &authItem) { authItemPointer -> Bool in var authRights = AuthorizationRights(count: 1, items: authItemPointer) let authFlags: AuthorizationFlags = [.interactionAllowed, .preAuthorize, .extendRights] let status = AuthorizationCopyRights(authRef!, &authRights, nil, authFlags, nil) if status == errAuthorizationSuccess { if !registerSMAppServiceDaemon() { return false } return true } return false } } } Error Details Unable to register Error Domain=SMAppServiceErrorDomain Code=1 "Operation not permitted" UserInfo={NSLocalizedFailureReason=Operation not permitted} The likely cause of this error is that /usr/local/bin/test is being bundled. However, based on my understanding, since this is a non-sandboxed application, the binary should be accessible as long as it is run as root. Trying post as mentioned in the response, placing the test binary under Contents/Resources/ allows SMAppService to successfully register it. However, executing the binary results in a different error. Here is the plist at that time. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.example.agent</string> <key>BundleProgram</key> <string>Contents/Resources/test</string> <key>ProgramArguments</key> <array> <string>Contents/Resources/test</string> <string>login</string> </array> <key>RunAtLoad</key> <true/> </dict> </plist> Here is the function at that time. private func executeBin() { let bundle = Bundle.main if let binaryPath = bundle.path(forResource: "test", ofType: nil) { print(binaryPath) let task = Process() task.executableURL = URL(fileURLWithPath: binaryPath) task.arguments = ["login"] let pipe = Pipe() task.standardOutput = pipe task.standardError = pipe do { try task.run() let outputData = pipe.fileHandleForReading.readDataToEndOfFile() if let output = String(data: outputData, encoding: .utf8) { print("Binary output: \(output)") } task.waitUntilExit() if task.terminationStatus == 0 { print("Binary executed successfully") } else { print("Binary execution failed with status: \(task.terminationStatus)") } } catch { print("Error executing binary: \(error)") } } else { print("Binary not found in the app bundle") } } Executed After Error Binary output: Binary execution failed with status: 5 Are there any other ways to execute a specific binary as root when using AuthorizationCopyRights? For example, by preparing a Helper Tool?

Fresh Project Using Insecure APIs (_sscanf, _strlen, _fopen, malloc) in Binary
Hello Apple Developer Community, I recently created a fresh project with: No dependencies No additional written code After generating the iOS build, I navigated to the build folder:"build/ios/iphoneos/Runner.app" Then, I ran the following otool commands to inspect the binary: otool -Iv Runner | grep -w _strlen otool -Iv Runner | grep -w _malloc Surprisingly, I received positive results, meaning these functions are present in the binary. My Questions: Why is a fresh project (with no extra dependencies & No additional written code) including these APIs in the binary?

Add static c library to xcode/swift
Hi, I want to build an ios app that uses static c libraries. For reference, i did the following as a test: Compiled a simple c date and time program with clang -c -arch arm64 -sysroot <iPhoneOSSDK_path> date.c -o date_arm64.o Created the static lib ar rcs libdatetime_arm64.a date_arm64.o Added the lib in my Xcode project. Added the (.a) file in Build Rules -> Link Binary With Libraries Included the (.a) and (.h) file path in Build Settings -> Search Paths -> Header and Library Search Path Created a Bridging-Header.h file where I added #import "date.h" In my App.swift file, I called the function for getting the date and time let dateTimeStr = String(cString: get_current_datetime()) print("Current Date and Time: \(dateTimeStr)") After doing all the steps above, I am met with the error - Cannot find 'get_current_datetime' in scope Is there any other method to use static c libraries in xcode?

Still possible to use XCode for local MacOS development without a bundle identifier?
I have used XCode for decades as my default C/C++ programming IDE. I write code that I run locally on my Mac, via "Sign to run locally". Typically this has always "just worked". I am now using MacOS 14.7 Sonoma, and I suddenly find I cannot run my code projects because I cannot dynamically load unsigned libraries. "not valid for use in process: library load disallowed by system policy" BUT - it appears that to allow my local MacOS code to bypass this requires I have a bundle identifier to modify entitlements. Which in turn requires a developer account which I don't have. Is this all correct? Is there any way to have code run locally and use dynamic libraries as I've done previously? Any advice is much appreciated.
