Question 1

How do I observe multiple properties at once with Observable?

Accepted Answer

Observable focuses on single value observation; for multiple properties, you need to set up separate observers or manually combine them, unlike frameworks like Combine that offer operators like combineLatest.

Question 2

Observable vs Combine: which should I use for my iOS app?

Accepted Answer

Choose Observable for lightweight, simple observation needs with better memory management and Swift integration. Use Combine if you need advanced operators, error handling, and native iOS 13+ support, despite its steeper learning curve.

Question 3

How to handle errors when observing values in Observable?

Accepted Answer

Observable does not have built-in error handling in its observation callbacks; you must manage errors within the value changes or wrap them in custom types, unlike Combine which provides dedicated error propagation.

Question 4

Can I use Observable with SwiftUI?

Accepted Answer

Yes, Observable can integrate with SwiftUI by driving state changes via observables, but it's not a direct replacement for @State or @ObservedObject; you'll need to bridge observations manually for UI updates.

Question 5

How to manually dispose of an observer before the disposal block runs?

Accepted Answer

Call the dispose method on the Disposable object returned by the observe method, or manage it through a Disposal collection, as detailed in the memory management section of the README.

Question 6

Is Observable thread-safe by default?

Accepted Answer

Observable itself doesn't enforce thread safety, but you can specify dispatch queues for callbacks to make updates thread-safe, such as using DispatchQueue.main for UI-bound operations.
