I can download the latest Xcode, but must I also be running at least iOS 9 to be able to develop an app and run it on my device without being a member of the developer program? I've got an iPhone 4 which cannot be upgraded any further from iOS 7.1.2.
There are certain features you are prevented from working with on iOS when using free provisioning. See the link in the notes below.
Free provisioning/testing on your device:
• Select your account, hit the “View Details” button and wait for them to load.
• Now create the 'signing identity' used to create a provisioning profile used for device testing - Hit the “Create” button next to the 'iOS development' label. When completed, hit ‘Done’.
• Connect your device and select it as build destination via the 'active scheme' dropdown to the right of the play and stop icons.
• In target's 'General' tab/settings:
• b. Set team id as your apple id
• c. Hit 'Fix Issue' button below the provisioning profile warning
- You may have to ‘Fix Issue' more than once - keep at it so Xcode can step thru them as needed.
• Run your app with your device selected.**
Notes:
- There is a limit to how many apps you can build and test to your device.
- Maximum number of devices allowed not known exactly, but if same as paid account, the limit is 100
- What you can/can't do w/free provisioning is listed here:
- If this is about creating an .ipa to manually hand off, select Build For Archiving under the project menu, not ‘Run’.
- *If you have, or plan to have, a paid developer account, be sure to use a unique/different apple ID for each account.
- **Free accounts may experience issues launching apps on the watch for the first time.
Workaround: Launch the app manually on the device and click “Trust” when the security sheet appears. You should then be able to launch the app from Xcode.
