I know in iOS developer program, a developer can use an ad hoc distribution profile to build an app, and this app is for testing purpose and can be installed on up to 100 devices.
Is there such a limitation for app developed with a Enterprise program account? And since this app is for internal use, does the employee's device need to be configured somehow to use this in-house app?
And is there any technical problem if I distribute the in-house app (for free) to a larger audience via a web link or email? I know this can be interpreted as violation to the Enterprise program, I am just wondering if this is technically doable.
There is no limitation on how many devices you can install the enterprise app. All you need is properly configured provisioning profile and signing identity and the UDID in the provisioning profile. I do believe you can distribute ad-hoc similarly as with normal iOS developer account, even easier.
There is much information available on StackOverflow already:
- IOS Enterprise Distribution Through OTA
- Enterprise distribution of iOS applications
- iOS Developer Enterprise Program
- iOS Enterprise Deployment / Expiration
- iOS enterprise account for distribution
- iOS Enterprise Developer Program
- Deploying ios apps wirelessly .Enterprise apps
And many more: https://stackoverflow.com/search?q=ios+enterprise
Please read through those first and you will get most of the information you need.
Beginning iOS 9, another important consideration is on first install Apple prompts you with an 'Untrusted Enterprise Developer' prompt. This requires you to go to Settings: General > Profiles and select 'Trust X' for the correct profile.
Not a show stopper. However, an important consideration if you need to do a large distribution as testers need to be informed.
