Xcode - Error creating LLDB target

Question

I\'m getting this error whenever I build in XCode 6 beta 4. It seems to be making my app insanely slow.

Warning: Error creating LLDB

Answer 1

Double Check Build Settings => Valid Architectures for both Project and Target.

Mine used to say: arm64 armv7 i386 (The one causing the error was i386)

I replaced it to : arm64 armv7

I hope that helps.

Answer 2

In my case I had to change Build Active Architecture Only to YES for the Debug configuration.

Answer 3

My "Architectures" included arm64 but I had to add arm64 to "Valid Architectures" in the target.

Answer 4

This warning is solved by changing Build Settings :

1. Select Project -> Build Settings

2. Change 'Architectures' to 'Standard architectures (armv7, arm64) - $(ARCHS_STANDARD)'

3. This will prompt an alert stating iOS 5.1.1 and above are supported. Click 'Change Deployment Target to 5.1.1'

4. Repeat steps for Target (if not changed automatically)

Also, this is preferred build setting since Apple is forcing developers to build apps on 64 but architecture. Apple document Link

Answer 5

Did you use Architectures=$(ARCHS_STANDARD_32_BIT) and run your app on a 64 bit device? (iPhone 5S or iPhone 5S simulator)

Apple seems to be stricter with apps which don't support 64bit. So if there is no specific reason, I think it's better to include arm64 in your build architecture

NOTE ABOUT 64-BIT ARCHITECTURE

An app extension target must include the arm64 architecture in its Architectures build settings or it will be rejected by the App Store. Xcode includes this architecture with its “Standard architectures” setting when you create a new app extension target.

If your containing app target links to an embedded framework, the app must also include the arm64 architecture or it will be rejected by the App Store.

For more information about 64-bit development, see 64-Bit Transition Guide for Cocoa Touch or 64-Bit Transition Guide for Cocoa, depending on your target platform.

Answer 6

In Xcode 6.4 , Swift 1.2. I had to edit both the Project and Target to the correct arm verisons (arm64, armv7 and armv7s). Take a look:
