I'm developing iOS application for my customer. At final point he asked me to share "preview" of an app via link before he could pay me for it. How do I do that?
How do I show my iOS app to someone, is there any other way aside from uploading it to AppStore and therefore making it public and needing developer account (I don't have at the moment)?
If I upload an app to AppStore, is it possible for my customer to "steal" and save it (through installing to jailbroken device for example and copying app with file manager), I suppose this is how users of jailbroken devices download and install paid apps for free using torrents?
What is the common practice of doing this, I mean demonstrating app in development to customer? On my own device? Bringing laptop with Xcode installed and using customer's device?
