问题
Working with my first application for learning purposes. It goes well but has met into a problem with Xcode. When I try to run the application on the iPhone simulator this message always pops up "This app could not be installed at this time."
What is wrong? There are no errors when trying to build the app. Has tried to clean the build. Reinstall pods. Restarted Xcode. Erased all settings on the simulator device, however, the problems still exist.
The error message does not give me any information. Is there another logfile I could look into or something?
回答1:
I managed to find the problem. The problem was that I had added some keys to a property list file that was not valid. I found the error by looking in the log file that was located here: ~/Library/Logs/CoreSimulator/
回答2:
Reset the simulator:
Hardware -> Erase All content and settings...
Clean your project:
shift+cmd+K
shift+opt+cmd+K
This should fix your issue

I know the question has been answered but for others encountering the same issue I suggest following:
Check simulator logs, if its printing something useful. First, selecte simulator then from menu option open Debug -> Open System Logs.
Make sure only 1 simulator is running.
Delete the older version of app from the simulator.
If you importing a custom framework, make sure custom framework->bundle-id is not same as currentAppProject->bundle-id. If you are not sure then simply change the bundle-id of current project.
Also some of the simulators can be buggy -> Simply change the simulator, it may resolve the issue, for me changing the simulator worked.

For anybody wasting time on this obscure error. If you don't have any relevant logs and all the other answers fail, you might check if you recently added a framework that for some reason (didn't investigated why) can't be embedded, only linked. Happened to me with GoogleMaps for iOS.
回答5:
I resolved this issue to remove DerivedData from Xcode Preferences. and also Restart the simulator from Hardware.
回答6:
Found issue in ~/Library/Logs/CoreSimulator//MobileInstallation
WatchKit 2 app extension's NSExtension.NSExtensionAttributes.WKAppBundleIdentifier value does not match WatchKit app's bundle ID
回答7:
Changing the CFBundleShortVersionString in InfoPlist.strings to match the one in info.plist fixed this for me. I had to use the simulator's "Erase All Content and Settings" after making this change.
Trying to launch on a simulator with iOS 9.0 (instead of 11.2) gave this error instead, which helped me to find more answers on what's apparently the same issue:
The operation couldn’t be completed. (LaunchServicesError error 0.)
回答8:
rm -rf ~/Library/Developer/Xcode/DerivedData/
回答9:
Just restart simulator to fix it in my case.
回答10:
I was seeing this on all simulators and all devices. Uninstalling the app would work once, but it continued to fail on me.
The fix was to wipe out all my project's pods:
pod deintegrate
And then re-install again:
pod install
This was with XCode 9.3 and iOS 11.2/11.3.

Occurred to me when I switched branches with another developer who was using a different version of CocoaPods , Deleting derived data folder worked !
回答12:
Just quite the simulator and start again works for me. In my case the error always occur if I change the bundle identifier and run afterwards the iPhone X simulator.

I encountered this error, but it had nothing to do with my Info.plist or Cocoapods. I had mistakenly deleted a duplicate NotificationServiceExtension group in my Xcode project, which caused me to end up with a NotificationServiceExtension target that had no source files (I only need one source file to integrate/piggy-back off of the Urban Airship SDK's rich notifications).
After reverting the commit where I deleted the duplicate group and then deleting the correct duplicate group (the one that didn't list the source file as being part of the target), I was able to build and run just fine.

To add a bit of additional info here. While Xcode is completely unhelpful about telling you why the app couldn't be installed, the console has quite good error messages. Just launch Console.app (Applications > Utilities > Console) and filter the output by installcoordinationd.
It'll give you something like this that describes the error:
installcoordinationd -[IXSCoordinatedAppInstall _onQueue_acquireAssertionAndDoInstall]_block_invoke: Installation for identifier:com.acme.location-thingy uuid:blah-blah-blah-foo intent:IXCoordinatorIntentInitiating creator/appDRI:InstallCoordination Simple SPI userInitiated:N state:IXAppCoordinationStateWaitingForInstall> failed: Error Domain=MIInstallerErrorDomain Code=99 "WatchKit v3 app has disallowed Info.plist key: NSLocationUsageDescription" UserInfo={LegacyErrorString=WatchKitAppIllegalInfoPlistKey, FunctionName=-[MIExecutableBundle hasOnlyAllowedWatchKitAppInfoPlistKeysForWatchKitVersion:error:], SourceFileLine=1841, NSLocalizedDescription=WatchKit v3 app has disallowed Info.plist key: NSLocationUsageDescription}
Hope this is helpful to someone!

I encountered this error while developing my first WatchKit app. Followed guidance from @PureRushh, @Antonioni and others to dump the contents of:
~/Library/Logs/CoreSimulator/CoreSimulator.log
The log contents led me to the error. I'll include the details in case others encounter this error while developing WatchKit apps.
Log message:
com.apple.dt.Xcode[89555] : installApplication:withOptions:error:: Error Domain=IXUserPresentableErrorDomain Code=1 "This app could not be installed at this time." UserInfo={NSLocalizedDescription=This app could not be installed at this time.,NSUnderlyingError=0x7f9ab87d1f20 {Error Domain=MIInstallerErrorDomain Code=101 "WatchKit 2.0 app's bundle ID com.somecompany.AirTime2.watchkitapp is not prefixed by the parent app's bundle ID followed by a '.'; expected prefix com.somecompany.AirTime."
Cause: I had modified the value associated with the BundleIdentifier key in the Info.plist (via General-> Bundle Identifier) of the parent app to match a URL Type (for SSO redirect); however, I failed to update the WatchKit App Info.plist value associated with the WKCompanionAppBundleIdentifier key (see second bold line).
Fix: Modify the WatchKit App Info.plist value for the key WKCompanionAppBundleIdentifier to agree with parent app's bundle ID
