I have a project that builds 5 binaries from 5 different schemes. Building each one of them separately takes around 2 minutes, with a large part of time spent on linking (lto I guess). I have a dummy target that builds all of them in parallel - I never managed to successfully build it, it goes on for 40-50 minutes and I just lose patience. What happens is, all the compilation is done ok, but when linking starts, 10 linker processes are spawned (5 binaries x 2 architectures) and they seem to never finish. While they are running, top shows a kernel_task using a lot of cpu (>100%) and the instances of ld using around 20-30 each. This is all happening on m1 macbook air 8/256. My guess is that it is a combination of RAM pressure, thermal throttling and the OS aggressively shuffling the 10 processes over the 8 cores, leading to lots of cache misses and possibly swapping. Is there any workaround I can apply - possibly some xcode setting to limit parallel jobs to 4-6 or something like that.

I figured it out. The scheme that I was using was originally intended to handle the WidgetKit Intent configuration. So in the scheme itself, it had a Siri Intent Query inside the run step. So all I had to do was create a new scheme that was intended to test the Widget, and the query was no longer there. It then ran without triggering it.

Hi there. Your Xcode Cloud build may be failing this way because the workflow is still looking for that scheme. Can you confirm that your workflow's build actions reference the correct scheme? Please ensure that you have pushed any changes to your scheme to relevant branches that your Xcode Cloud workflows build from.

We use a direct link mechanism in our app that attempts to open the app if it's already installed; otherwise, it redirects the user to the App Store. However, when the app is not installed, Safari displays an alert saying: Safari cannot open the page because the address is invalid. This popup appears to be caused by attempting to open a custom URL scheme that doesn't resolve. what is the recommendation from apple to have a smooth transition to our mobile App Here’s a sample link we’re using: https://new.oneclear.com/Asset/fe5f7fb6-205a-40f8-9efe-71678361aa2c?t=NTA0NQ==
Yes, with something like this ...xcodebuild test -scheme YourAppScheme -destination platform=iOS Simulator,OS=9.0,name=iPhone 6Replace your project's scheme name in for 'YourAppScheme'Used to be you had to export/share the scheme (go to manage schemes in Xcode) to get this to work. Not sure if that is still the case. Just a warning.You can play with the destination settings to pick different devices, etc.Cheers.

I am using custom url scheme to transfer some data from WKWebView to App. The JS code I use in WKWebView is similar to this: try{ window.location.href = 'bsfit://'+window.some_custom_data; }catch(err){ alert(err); } Before iOS 15.4, this has worked perfectly. When tested on iOS 15.4 Beta5, I got an error TypeError: Invalid URL. Is this change intended in iOS 15.4 regarding custom URL schemes? Since I can't change the existing app code, is there a workaround? Thanks.

By default, StoreKit Testing in Xcode is disabled. After enabling this by selecting the StoreKit Configuration file for the scheme, you will then be able to complete purchases in both iOS and watchOS for this Backyard Birds project. For information see StoreKit Testing in Xcode. If you continue to have issues, please provide what errors you are seeing and how to reproduce them.

I haven't seen the same message till now.Me neither, although it seems likely that the “testable” mentioned here relates to the Xcode scheme.@dpeace1982, you should check to see if the tests referenced by your scheme (in Product > Scheme > Edit Scheme > Test > Info > Tests) make sense.Share and Enjoy — Quinn “The Eskimo!” Apple Developer Relations, Developer Technical Support, Core OS/Hardware let myEmail = eskimo + 1 + @apple.com

Hi,The 'Host' parameter of the URI atrribute (in this example:- 'token'), can be retrirevd via the 'identifier' property of AVContentKeyRequest.This will work for Just In Time acquisition of the key(s).If you need to prefetch the keys, you will need to carry the assetId out of band or parse it from the playlist (EXT-X-KEY...)

I couldn’t find a deep link tag There is Universal Links, but that’s not entirely accurate because your focus is on URL schemes. For URL schemes I recommend Core Services, which is vague but at least it’s something I track (-: You’re asking about iOS, right? Because on macOS we have the activateFileViewerSelecting(_:) method an NSWorkspace. I have some general advice on this topic in this post, and the posts its links to. AFAIK none of the documented schemes do what you want. I recommend that you file a bug requesting an iOS equivalent to the above-mentioned NSWorkspace API. IMPORTANT Don’t ask for NSWorkspace as a whole. That’s unlikely to happen on iOS. Rather, focus on that specific API. Please post your bug number, just for the record.

site didn't allow me to write scheme that's why I write url without scheme. I see. A really annoying restriction.

It seems that apps, which are generated with the latest version of Xcode, generate EXC_BAD_ACCESS when the iOS app is called by url-scheme. Do you have the same issues or any workaround?Steps to reproduce:1) Compile an app with an url-scheme2) call this app from e.g. Safari by using myapp://openThe app opens and then crashes with EXC_BAD_ACCESS
