I am trying to make my own iOS applications by using Xcode 7 and iOS 9.0. I have successfully been able to install the app on my own iPod by following Xcode 7 develop for iOS without developer account however when I run the application I get this error:
I had a quick look in the Settings app but cannot find a way to allow this application that I made. How would I 'trust' this application running iOS 9?
The following instructional steps to accomplish this purpose are taken from: http://iphonedevwiki.net/index.php/Xcode
My findings and actions are provided under each step.
1. Create a self-signed code-signing certificate with the name “iPhone Developer” on the “login” (default) keychain using Keychain Access.
2. Open /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Info.plist (4.2 or below: /Developer/Platforms/iPhoneOS.platform/Info.plist). You may need root permission.
.plist file.3. Replace all occurrences of XCiPhoneOSCodeSignContext by XCCodeSignContext. There are three of them (XCode Version 3.2.4+).
4. Save the file and restart Xcode.
5. Make sure you have ldid on your Mac. Place a copy somewhere e.g. in /usr/local/bin.
/usr/local/bin.6. Create the a Python script ldid3.py right next to the ldid program. Make it executable. Fill it with:
#!/usr/bin/env python
from sys import argv
from subprocess import check_call
from os.path import basename, dirname, splitext, join
from tempfile import NamedTemporaryFile
app = argv[-1]
ldid_path = join(dirname(__file__), 'ldid')
obj_path = join(app, splitext(basename(app))[0])
if '-gta' not in argv:
check_call([ldid_path, '-S', obj_path])
else:
with NamedTemporaryFile('w+b', 0) as f:
f.write("""
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>get-task-allow</key>
<true/>
</dict>
</plist>
""")
check_call([ldid_path, '-S' + f.name, obj_path])
ldid3.py and stored it in the /usr/local/bin directory.chmod 777 /usr/local/bin/ldid3.py.7. Open iPhoneCodeSign.xcspec. This file can be found in [For Xcode 4.6: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Specifications/iPhoneCodeSign.xcspec]:
8. Change the entry in the file from calling codesign to ldid3.py.
sudo plutil -convert xml1 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Specifications/iPhoneCodeSign.xcspec<key>CommandLine</key><string>/usr/bin/codesign</string> with <key>CommandLine</key><string>/usr/local/bin/ldid3.py</string>.9. Save the file and restart Xcode.
10. Create a file /var/mobile/tdmtanf on the device, to enable Apple's "TDMTANF bypass" in installd (warning: doing so will also put you in a sandboxed GameCenter).
tdmtanf, SSH'd into my iPod, uploaded it to /var/mobile/, and reboot my iPod.I open my existing Xcode project and hit Run. It works in the iOS Simulator without any problems.
I make sure that Code Signing is set to use the certificate set up in step 1.
I build the app (Project > Build). A success message follows.
I grab my app folder TicTacToe.app from /Libary/Developer/Xcode/DerivedData/TicTacToe-cjgzmoxtflyegtfypsbxbuiuwxns/Build/Products/Debug-iphoneos/ and transfer it to my Windows machine to install onto my iPod.
In an attempt to install the app to my iPod, I drag TicTacToe.app onto the applications section of iPhone Configuration Utility, but I received this error message saying that my app "is not a valid mobile application."
I have also tried manually installing the app using iFunbox and the AppCake app found in Cydia. Both fail.
As a point of interest, because as I've Googled around, I've noticed many people mention the importance of this: I do have AppSync installed. (Sorry for the huge screenshot. If I should take it down, please let me know!)
So despite following the instructions closely, several times, my app is not recognized by iPhone Configuration Utility as a valid app. I cannot install the app manually using programs like iFunbox, or Cydia apps like AppCake.
I suspect the app is indeed invalid, but having followed the instructions carefully, I'm not sure why.
Can anyone tell me why my app is not valid, and what I can do to fix this, besides coughing up money that is?
You don't need to pay for an Apple's developer want the $99 option for a store certificate, billing and general code signing certificates.
Your personal AppleID is good enough to sign apps in Xcode and load them on a limited number of devices (5 or so) from your Mac to get started with developing. Once you need TestFlight or want to make a signed app that is reviewed - you need to pay, but get started for free.
Here’s how I would undo a previous paid AppleID - you might need Apple Developer support to help you release your AppleID from the paid program if you are reusing the same AppleID (and I encourage always reusing the same and not making new accounts when you run into a hiccup like this).
Instead, delete all Xcode copies you might have installed earlier - whether they are from the Mac App Store or downloaded and then install Xcode 7 from the Mac App store:
Once it downloads, run the app and go to the settings:
When you build an app for iOS, connect the iOS device and choose that AppleID to sign the app when asked.
Best Answer
Enterprise and other certificates have to be manually trusted on iOS 9 when they didn't have to on iOS 8 and earlier.
If you don't see "Profiles & Device Management" then your device needs to reinstall the app or get the appropriate profile from MDM / other enrollment. Also, if your network or system blocks any outbound traffic to Apple servers for time sync, OCSP/CRL or notarization checks, you will see errors or potentially have other challenges to run apps.
