How come Some devs submitting apps and don't know exact release date they just wait for apple approving their app but gameloft or EA for example know exactly the release date
Its the same for EA and gameloft too. They too have to wait for getting their apps approved. But instead of releasing the app as soon as its approved, they hold the release until a specific date. Thats how they know when the app will be out in appstore. Its not exclusive for EAs and Gamelofts either. Any dev can chose to set a release date. Though most dont care about release dates and just want the app out as soon as its approved.
