Lottie VS SnapKit

Lottie still has a lot of support (backed by Airbnb) and just got a big performance upgrade on iOS. However, there are competitors cropping up (like Rive) with the aim to be more lightweight and not tied to After Effects.

Lottie - After Effects vector animations

When I wrote my app which needed Lottie animations, I found LottieXamarin library, but that only works with Xamarin.Forms not with MAUI. I tried to update it, however I've run into multiple issues and at the same time I've realised only older Lottie versions can be binded, because from March of 2019, Lottie is a Swift library, which means it can't be binded easily.

It's probably made with Adobe AE or similar, and exported in Lottie format (SVG-data like + assets) to be loaded and rendered with the Lottie library for iOS (https://github.com/airbnb/lottie-ios) which I presume already comes with SwiftUI-compatible API.

The HN thread also mentions Lottie from AirBnB and IconVG from Not-an-official-Google-product.

I think there might be one but not sure how up to date it is: https://github.com/airbnb/lottie-ios/tree/lottie/objectiveC

I’ve been using Xcode for the last 13 years or so, and my advice is - us whatever is comfortable and makes sense to you. I use all 3: code*, storyboard and interface builder (xib). They all have their strengths and weaknesses. Storyboards are nice for quick simple screens with table/collection views and cell templates, but sucks when working in a team (merge conflicts on xml files is not fun). Interface builder has the advantage of being really quick for standalone viewcontrollers and views (after some code that takes away the boilerplate part of loading views from nibs) and minimized the git issues. And code is fun when you’re using anchors and frameworks like snapkit (https://github.com/SnapKit/SnapKit) but even when I was doing visual constrains using strings it was fine. Anyway, just try to learn a bit of everything and see what resonates with you. There are no right answers, just preferences.

If you need to use Auto Layout, I recommend using a wrapper SDK like SnapKit https://github.com/SnapKit/SnapKit that is less verbose and less error-prone and assigns translatesAutoResizingMaskIntoConstraints and isActive automatically.

With a library like SnapKit, you can still have the terse, declarative coding style of UIKit. Hell, I once wrote my own poor-man's version of SnapKit on a whim because writing out constraint code manually got tedious.

SnapKit (19k⭐️) has been providing almost the same thing for years. It is already a standard for many companies.

With something like SnapKit (I actually rolled my own poor man's version in like 10 minutes, before learning that SnapKit existed), SwiftUI no longer appeals to me because of it's declarative-style DSL.

This. And if you want to learn AutoLayout without the verbosity/complexity of Apple's own APIs, I would look into using SnapKit.
