Jetpack Compose Composables/Widget Catalog - android-jetpack-compose

Sorry to disturb but I have been searching for some time now and have not yet found a good place to see the widget catalog of Jetpack compose like the one used for Flutter. I want something where there is some kind of reference table or something that helps senior devs get up to speed in a glance or some short videos/demos just so that we get a feeling what is possible. The following links helped me get up to speed really fast when I wanted to learn Flutter and a similar thing for Compose would be great for intermediate/senior devs to get a very quick jumpstart.

I found this, but, keep in mind that community is sharing composables, not sure if any official site (a google's one) about it.
https://composables.co/
They're preparing a ebook and waiting to more composables to de shared there.

Zapier cli : how can I retrieve my pushed source code?

I've been converting my zapier app with zapier-cli and I've used the push command to send some beautiful precious features in my app.
Unfortunately - and I blame myself for it -, I didn't push it on github or either not in any versioning tool. And of course I can't access my code anymore -_- So my question is, is there any way to retrieve or pull my source code from the web app?
I've checked the documentations and I couldn't find any pull-likely command
ANd On the web app, there is no way to see the code from the developper platform.
Does someone know if there is a way ? Any advice (except for versioning advice) would be great :)
David here, from the Zapier Platform team.
Bad news and good news. First off, there's no direct way for you to pull it down.
The good news part of that is that we do keep a copy of a lot of pieces of it (so we can run it!) so if you write into partners#zapier.com and reference this question, we should be able to sort you out.
Note that this should not be considered a primary backup method and it's important to always have access to your code. Do be careful in the future. :)

How to get everyone to see everyone else's photos in an instagram-like app

I am a first time iOS developer trying to build an iOS app from the ground up. It is for a photo-sharing startup that will have similar functionality to Instagram.
I am not sure how to approach the sharing/viewing aspect. Would I use something like Parse or Google cloud storage? It is an iOS only app, if that helps. Given that we are just a startup, a long trial or a cost per GB is fine, but I don't want to be stuck with something expensive if we start getting a lot of photo uploads.
Given that I'm the only developer, I'm hoping for something that doesn't require me to learn too many new technologies. Any help would be greatly appreciated!
Parse.com, the API is fairly easy to use. The free plan has a lot of functionality and it scales up well.
That's really a tough question. You first want to research each company and weigh the pros and cons with selecting each service. The Google Cloud and Google App Engine (while they do work extremely well together) are going to be a little less "centralized" since they are essentially marketed as separate services. Parse does have that "centralized" feeling since all of their services are designed to work together.
Another nice thing about Parse is that it has build in support for iOS local datastore which means even if your users don't have an internet connection the request will be queued until a connection is made. If you go with a service like the Google Cloud then you would have to implement that on your own or just not have offline functionality.
While Parse looks like a good solution for you, it would be hard for someone to answer your question with a definitive solution as that is up to you exactly how you want your product to work. Just continue to research other solutions as there may be something better and more suited for your exact needs. You may want to build a small prototype on one platform before dedicating all of your development to that platform.

iOS 7 embedded calendar api

I'm fairly new to iOS development, I've been asked to write an application that moves around days in a calendar. The graphics designers thought it would be a good idea to have an embedded scrollable calendar so the user could navigate easily through dates.
I'd love to post an image for what I want but I don't have the reputation yet to do so.
This calendar view looks just like the native calendar app on iOS 7 but it's just a sideways scrollable choosing date of the month you're in and it only take a small portion of the screen. Would anybody know if there's a framework I could use to achieve similar results?
Thanks in advance!
I know it's a little late, but I'll just post it here in case other people has the same problem.
A few months back, I had the exact same problem.
I couldn't find exactly what I need, so I had to implement it myself with UICollectionView
Anyway, after finishing my project, I've decided to make a library based on it.
This should be easier to use than any other calendar library.

Hope it helps :)
There will most likely not be a component that does exactly what you want. A good thing to do in a situation like this is search on Github and filter by language, then sort by popularity.
Here is an example search to get you started, for "calendar":
https://github.com/search?l=Objective-C&o=desc&q=calendar&ref=cmdform&s=stars&type=Repositories
A few promising candidates from that search:
https://github.com/leverdeterre/CalendarIOS7
https://github.com/fggeraissate/FFCalendar
https://github.com/square/objc-TimesSquare
https://github.com/jaykz52/CKCalendar
https://github.com/min/MNCalendarView
There are tons of these, all slightly different, so you'll need to do some digging to find one that is most similar to what you want to accomplish.
In general, any implementation you find or create yourself should probably use a UICollectionView to accomplish this.

iOS sample projects to learn from

I am just starting iOS development. I read some tutorials, watched stuff on iTunes U and wrote some sample code myself. Now I want to take the next step. I want to learn about best practices for iOS development in XCode.
Are there any well written and well organized iOS projects that one could take a look at?
(As I see it, iOS is not exactly the place for open source enthusiasts, however.)
Thanks
Mike.
I agree with several of the other answers that state that looking at many, many projects for mini-examples of what you want to do in your own app is the way to go.
However, you asked for an example of an app demonstrating best practices.
You could do worse than to read Matt Gallagher's blog, Cocoa with Love from beginning to end. However, the app example you asked for is right here.
Not only will it show a variety of techniques, some novel design and best-practices, but also he points out where he feels that he might have done something better.
It's a great read.
I would suggest the following process: (it worked for me)
Think of an advanced app. that you eventually want to be proficient enough to create.
Make a top-down problem-solving tree containing the necessary skills required to build your final app.
Use this tree to divide your final app. into 'sub apps'. Start at the bottom of the tree, find a tutorial specifically for that skill, and make a "Hello World" app. that uses that skill.
Keep progressing upwards, creating 'sub apps' as you go.
When you are finally ready to make your final app. (it will take a while), you will have a good handle on how iOS development works. It will also be a great test of your knowledge via direct application!
Getting the hang of iOS development can be tricky; it really does require a top-down approach, and every online resource I've found takes a linear one. The only way that I think a linear approach to learning iOS development would be manageable, is to take it one small task at a time.
As for specific resources, I always google "[what I want to do] iPhone SDK" and browse the tutorials and forum posts that come up.
Here are some open source iOS apps. However, they aren't very well documented and are also very advanced.
TKAWebView - A subclass of UIWebView that handles authentication and downloading.
Welcome to your Mac - An iOS app. to VNC into a PC/Mac and do some cool stuff.
InAppSettingsKit - A settings screen creator for your apps.
Good luck!
The people behind the Parse platform have made two complete projects.
For each project there is the complete source code, a tutorial and the resulting app is also available from the AppStore.
Anywall: https://parse.com/anywall
Anypic: https://parse.com/anypic
They both rely heavily on the Parse platform as the data source, but you still get a feel for an iOS project.
Molecules is a great open-source app that uses 3D OpenGL to render complex models of molecules.
Just keep coding my friend. You'll learn over a period of time. The best way to get dirty in a mud fight is to jump into it... Weird analogy but you get the point.
Maybe someday, we all will learn from you then !
Like you said there many and many source codes are available internet, but most are incomplete.
I found some Open source codes of REAL application currently available through Apple app store are given here
Free iPhone App Source Codes of real apps
and also, you can find many answers here on stackoverflow question - Are there any Open-source iPhone applications around?
You can download free IOS sample projects from http://devcodemarket.com
I realize this is an old thread but I've also been looking for good objective-c code examples recently and I just realized that TextEdit's source code is available at the Mac Developer Library webpage.
Also, here are some popular objective-c libraries that have caught my attention:
CocoaPods
AFNetworking.
you can also go through UICatalog from Developers Library and download the sample code. just google it and you will find a project containing all basics of iphone.
I don't think there is any perfect project that can demonstrate all the qualities of great code. Developers have stylistic preferences and may make mistakes. That said, you should look at a lot of different projects and try to look at the conventions used.
I'd suggest starting on GitHub. Besides for seeing code, you'll see what libraries are out there, which may help further your projects later on. Here's the Objective-C page on GitHub.
(Also, I (GitHub link) think you're wrong about iOS devs not being in favor open source. Yes, there's money to be made, but you can't sell a CSV paring library on the App Store as is.)
Have a look at https://github.com/mozilla/firefox-ios
That is Firefox for iOS, written in Swift.
Cocoacontrols has a wide range of controls written using Objective-C & Swift.
I believe these days, this is one of the most famous website for iOS Developers.
But, before you jump onto this, you have to learn Objective-C & Swift very well, so that you will understand how to use the controls in your app which makes your app smooth.

How to build a search with new features?

I want to build a search engine for my project this year, so what I
need to implement in my project to get best grade (I need new ideas
for search for video or audio...). How and where can I start to learn
about this topic. I want to use Java and any framework on it. I know
that I can't build a Google Search, but I need to implement a new idea
in my project to get best grade.
I'd suggest that you start with an open source search engine like Lucene (Java or .NET) and start adding features on top of the plaform. Perhaps you could build a plugin for searching camera meta data (I.E., EXIF)?
PS. You might want to start marking the correct answers for the 20 questions you've already asked. Having an acceptance rate of 21% doesn't really give the recognition to those who work hard to answer your questions.
