Vimeo has pretty much always had a shockingly* high price for their slightly-better plans, since they insist on covering their costs from subscriptions from the get-go. I'd be pretty confident they wouldn't bait-and-switch to grab some more cash (not the least since they're not the dominant video hosting provider). They compete on service and stability.

Swift language features keep improving, and it's easily my favorite language to code in. The developer tools, on the other hand are complete trash. A large iOS app written in Swift can easily take 5 minutes to compile, while the equivalent Objective-C app would take 20 seconds. Additionally, Xcode is one of the most unstable IDEs out there. Simple things like refactoring a variable name or looking up a function declaration are barely working.
They tried to improve compile times with Xcode 10 though. Should be getting better. Same goes for autocompletion, but that's just taking their word for it. I've got beta installed, but did not spend much time with it (for some reason the main project I'm working on is failing to compile in it, did not bother to investigate yet).
