Yeah, I’ll keep you posted. The guy who has been offering tech support is going to follow up with the bug reporting engineer who gets the report as well. Here’s what I tried and listed in my report:
Mid 2012 MacBook Pro
OSX 10.10.1
Xcode 6.1.1 (also later tried 6.2 beta 4)
Application Loader 3.0
Keychain Access 9.0
Creating certificate signing request, certificates, App ID, and provisioning profiles on one MacBook Pro leads to “App Installation Failed. The application does not have a valid signature.” when trying to test the app on iPad 3.
Replicating same steps in same order on a different MacBook Pro results in correct build and ability to test on same iPad 3. Both MacBooks have the same specs and software.
Steps to Reproduce:
Steps to Attempt Correction:
1.) Uninstall Xcode 6.1.1 and Restart MacBook Pro
2.) Re-install Xcode 6.1.1
3.) Restart MacBook Pro
4.) Reset Keychain Access 9.0 to Default
5.) Run Keychain Access First-Aid
6.) Revoke All Certificates from developer.apple.com
7.) Delete App IDs from developer.apple.com
8.) Delete Provisioning Profiles from developer.apple.com
9.) Remove Provisioning Profiles from iPad 3 via Xcode 6.1.1
10.) Delete App Developer Account from Xcode > Preferences
11.) Create new Certificate Signing Request in Keychain Access 9.0
12.) Create new Development and Distribution Certificates on developer.apple.com using Certificate Signing Request
13.) Create new App ID called “MyApp” on developer.apple.com
14.) Create Development and Distribution Provisioning Profiles using MyApp
15.) Download Certificates and Provisioning Profiles
16.) Add Developer Account via Xcode Preferences
17.) Refresh Account to display Development/Distribution Certificates & Provision Profiles
18.) Add Development Provision Profile to iPad via Xcode > Devices
19.) Restart Xcode
20.) Open HelloWorld app.
21.) Set up Xcode to Automatically Manage Profiles as recommended by Apple Developer Technical Support (https://developer.apple.com/library/ios/qa/qa1814/_index.html#//apple_ref/doc/uid/DTS40014030)
22.) Attempt to test on iPad and receive “App installation failed. No code signature found error.”
23.) Uninstall Xcode 6.1.1
24.) Restart Computer
25.) Install Xcode 6.2 Beta 4
26.) Repeat steps 3-22
