Xcode debug build vs release build

I have fixed the issue.

I found that by running expo publish in the terminal and then building with the release archive scheme in Xcode, it notices the changes.

Now why that is required (maybe it isn't), I am unsure of.

If anyone has an any additional insight, it would be greatly appreciated.

EDIT: So it looks like when I run expo publish it updates the app.bundle and app.manifest. This must be what the release scheme looks at when building.

And after drilling down, you should be able to find the release folder with your release framework inside.

Xcode 7 - how to build Release target?

By default Profile and Archive build Release, so you could do Build for->Profiling to get a Release build.

You can also modify things to build different configurations, or add your own. Choose Product->Scheme->Edit Scheme. Then to make Run use the Release configuration, select Run on the left side and choose Release for Build Configuration on the right.

How do I produce an iOS Release Build that my client can sign on their end?

Most of these answers seem complicated and out dated. I think the simple answer is to make an archive with a Developer profile.

This is a solution which I am currently investigating for my own purposes (not fully tested):

You just need developer access (not team agent) to their account and create a Development provisioning profile that authorizes you to build the specified App ID (you need to specify the App ID, because it gets compiled in). Then Archive the app with the Development profile, and share the archive with your client. They can then re-sign the archive with their own Distribution profile.

One complication is that when you build an archive with a developer profile, the entitlement attribute get-task-allow gets set to true, but needs to be set to false for distribution, so you have to work around that by setting it manually your Entitlements.plist - see my question here: Can I archive with a Developer certificate, then re-sign it during submission with a Distribution certificate?

Quickest way to install Release build on device?

You should be able to go in to your Edit Schemes preference pane. You can change your Build Configuration to Release there. I would suggest creating a duplicate scheme in which you can build Release builds.
