Since the App Store's launch, iOS developers have earned over $86 billion.
Per a blog post by Buddybuild, the move will be instrumental in building "amazing developer tools for the entire iOS community".
The company said that it would stay in Vancouver - a hotbed of developer and engineering talent.
While Buddybuild will continue to serve its existing customers as a standalone product through its website, it won't accept new customers through that portal, coming into effect from today.
This deal also means an end of the Android app development that it just added in February 2017.
In March previous year, Apple chief executive Tim Cook announced his intent to launch a startup accelerator for the iOS developer community in India.
More to the point, it should make developing and iterating apps for iOS that much easier than before. There will be a lot of changes coming as a result of Apple acquiring Buddybuild, with the notable change being for Android users.
Buddybuild is a Canadian startup that focuses on creating developer tools for app developers.
Apple has had a very good start to 2018; and this is based exclusively on the performance of its App Store. Past year also saw Apple unveil a redesigned App Store with the release of iOS 11 in September.
Indeed, $300 million came in on New Year's Day alone, presumably as everyone made unwise in-app purchases to get through their hangovers.
Buddybuild was founded in 2015 by former Amazon employees Dennis Pilarinos and Christopher Stott. The platform supports code sharing on GitHub, GitLab and BitBucket including running of user interface tests along with beta testing and deployment to Apple's TestFlight service. The remaining roster of existing customers is an impressive one, including Mozilla, Hootsuite, Reddit, SoundCloud, FourSquare and The New York Times.
