To ensure the user’s privacy and safety as well as to protect the app developers’ commercial interests, Apple has created an elaborate process which requires each app to be digitally signed. A provisioning profile is one component of this signing process. To put it simply a provisioning profile determines if an app can be installed and run on a device. Appropriate provisioning profile must be present on the phone in order to install and run an app on that phone. For the developer there are 3 modes while creating iPhone apps: 1. Development mode: This uses a development provisioning profile. This provisioning profile specifies on which phones the app can run on. To enable your phone to run the development build, you need to provide the UDID of your phone to your developer. She will then include this UDID in the development provisioning profile and will send you a build which uses this provisioning profile. This build can then be installed and used on your phone. This also provide a great way to protect your app from casual hackers and competing startups, as they cannot install a run a build even if they manage to get their hands on one. One annoying limitation Apple has put on developers is that one development provisioning profile can only specify a maximum of 100 test devices. A build that uses development provisioning will work for 3 months (TODO: verify this) from the date of creation. 2. Ad Hoc distribution mode: This type of provisioning profile has all the advantages and limitation of the development provisioning profile, but the build that uses an ad hoc distribution provisioning profile will work for 1 year (TODO: verify this) from the date of creation. 3. App Store Provisioning Profile: This provisioning profile is used to create the final build which can be distributed via AppStore. The build which uses the App Store Provisioning profile can be installed only via AppStore. And will work forever (TODO: verify this).

To ensure the user’s privacy and safety as well as to protect the app developers’ commercial interests, Apple has created an elaborate process which requires each app to be digitally signed. A provisioning profile is one component of this signing process. To put it simply a provisioning profile determines if an app can be installed and run on a device. Appropriate provisioning profile must be present on the phone in order to install and run an app on that phone. For the developer there are 3 modes while creating iPhone apps: 1. Development mode: This uses a development provisioning profile. This provisioning profile specifies on which phones the app can run on. To enable your phone to run the development build, you need to provide the UDID of your phone to your developer. She will then include this UDID in the development provisioning profile and will send you a build which uses this provisioning profile. This build can then be installed and used on your phone. This also provide a great way to protect your app from casual hackers and competing startups, as they cannot install a run a build even if they manage to get their hands on one. One annoying limitation Apple has put on developers is that one development provisioning profile can only specify a maximum of 100 test devices.

App Store Provisioning Profile: This provisioning profile is used to create the final build which can be distributed via AppStore. The build which uses the App Store Provisioning profile can be installed only via AppStore. And will work forever (TODO: verify this).
