xcode github

I'm running OS X (10.12.1), Xcode 8.1 and Swift 3 on my MacBook Pro (all are updated automatically). For a MacOS application (not iOS), I want to show an alert when an invalid user entry is input. I've researched a zillion examples and tried many of them, but none work. And, a good number of them send my Playground into a loop (dreaded color wheel) from which I have to reboot (the latest of these is attached).My question is: What is the proper Swift 3 code to create an alert in the environment and the conditions described above occur?

How can I test an app developed in X-Code 6.4 on the iOS10 simulator?

Where can I find pro versions of X code that I can run on my Catalina MacBook Pro?

Hey, so I wanted to pull from the Github project repository and XCode asked me login again. Forgot my password so I tried a wrong one and now it keeps asking for my Username and Access token, when I actually just want to login with my password. Doesn't let me choose between the too, not even when adding the account through preferences. Anyone know how to just login with password and the reason for this -pardon me- absolutely idiotic choice of not letting the user choose?

When you are checking in an Xcode-based project into git (pushed up to github), shouldyou check in the .DS_Store files that appear? Or do these get re-generatedautomatically by OSX if they are not there (say, when you git clone a project?)

i update my mac to beta version and i'm facing issue in X-code simulator. its taking 5 minutes to set up , and lagging issue .

I am trying to configure my access to GitHub and no matter what I do I get the Authentication failed message. I have tried everything I know to try. I have even disabled two-factor authentication and just tried using a username and password which I know is correct. I simply want to make it work so that I can set a bot with OS X Server.Is there a guide somewhere which helps with troubleshooting access problems with Xcode repository configurations and GitHub. It appears to be completely non-functional.

Hi everyone Premise: it works with Xcode 14.2 I have a problem with fastlane and slather, it gives me an error that it cannot find the code coverage folder Here are some details Fastlane file slather( build_directory: ./DerivedData, scheme: MyApp, workspace: MyApp.xcworkspace, proj: ./MyApp.xcodeproj, output_directory: ./DerivedData/testResult, cobertura_xml: true, verbose: true ) Error: Exit status of command 'slather coverage --cobertura-xml --build-directory ./DerivedData --output-directory ./DerivedData/test-output/slatherOutput --ignore Pods/* --ignore fastlane/* --ignore build/* --ignore DerivedData/* --verbose --scheme ProjectName --workspace ProjectName.xcworkspace ./ProjectName.xcodeproj' was 1 instead of 0.

Can I create a GitHub account in Xcode and then delete it in Xcode and then create another different GitHub account in Xcode? Then delete that account and then recreate the original Github account again. Using GitHub accounts one-at-a-time. Is it possible, or not?

Hey guys, I have a strange problem. I am getting this error: Missing path (/Users/username/Documents/Development/Brief/Brief/Mapbox/MapboxCoreMaps.xcframework/ios-arm64_x86_64-simulator/dSYMs) from XCFramework 'MapboxCoreMaps.xcframework' as defined by 'DebugSymbolsPath' in its `Info.plist` file The interesting thing the same project pulled on other Macs works perfectly fine. Just my home MacBook Pro has this problem. The project itself is on Github. I checked the folders and they do exists. Have no idea what it wrong.

Hi allHaving had several issues with earlier versions (mainly - simulator trying to launch for about 5 minutes before failing, xcode suddenly quitting once or twice an hour, playgrounds taking 5 minutes to launch plus many others) I hoped that 9.3 would be better. Ha! Now it is far worseWhen I select storyboard it locks upWhen trying to quit it locks up.Simulator doesn't launch at all With these problems the program is totally unuseable.I have been learning to program for the last 8 months but a HUGE amount of my time has been wasted battling this program. I have tried all the suggested fixes, sent in a bug report, but all to no avail.From what I have read there are a number of people like me that have continual problems, but I know people who have no or very few problems. This is especially noticeable when I watch u-tubes of others using X code and how nicely it seems to work for them. This would seem to indicate a problem with my computer. It is a 2 year old iMac, 8 GB memory. I h

xcode-beta 10.5 can't add source control accounts like GitHub. On the source control tab I have checked Enable Source Control. My xcode 9.4.1 works fine.
