Hi,
I just startet using Xcode and tried to write one of my first little apps. By using the Xcode simulator it works just fine, but when I tried to use my own iPhone to test it, it wanted my password to get into my Keychain account. I forgot the password at that time and so to close this pop-up I hit "don't allow". Unfortunately every time I try to upload may code to my iPhone the Build fails. It says:
/Users/MaximilianFries/Library/Developer/Xcode/DerivedData/LED_Uhr-bqirsotpaupqywfdikvowlxmgksb/Build/Products/Debug-iphoneos/LED Uhr.app/Frameworks/libswiftCore.dylib: unknown error -1=ffffffffffffffff
error: Task failed with exit 1 signal 0 {
/usr/bin/codesign '--force' '--sign' '8B57842E538ECD83F378F14E79269DF3F311489A' '--verbose' '/Users/MaximilianFries/Library/Developer/Xcode/DerivedData/LED_Uhr-bqirsotpaupqywfdikvowlxmgksb/Build/Products/Debug-iphoneos/LED Uhr.app/Frameworks/libswiftCore.dylib'
}
I already deleted all files in the Derived folder and reinstalled Xcode, hoping it will ask me again for Keychain access. But it doesn't. Can anybody help me solving this?
