Myself and a team are starting a potential startup and one of the things we want to do is a mobile app. We have already identified the target audience to mainly be iPhone users. But here in the US there's still plenty of Android user so we've been considering using a cross platform framework like Flutter. I've seen a lot of praise that Flutter is easy to use and can help us deliver an MVP faster. My ideal situation is to start developing with Flutter and when the app is successful migrate it to a native iOS app using Swift. But is that possible at all? Or if we decide to go native when we already have a flutter app, do we need to start from scratch?
Developing a Flutter app is completely different from developing an Android or iOS app. It has different language, has it's own architechture with it's own packages/dependencies/plugins.
You cannot convert from one of them to the other.

I want to build a very simple gallery like app (which uses the Telegram bot API to fetch images from certain telegram channel). I want to have this app for both Android and iOS device. I guess either progressive web app or flutter could be used to achieve this. I have developed native android apps before, and wish to learn PWA or flutter along with this project.
So my question is, can I deploy this app to my iOS device without enrolling in the Apple developer program? Since this is only for personal use and I do not wish to publish this app on any app store. Also, do I need to have a Mac with Xcode to do this?!
Thanks in advance!
For developing a Progressive Web App for iOS, you won't need Xcode and a Macbook since it is basically still a website with enhancements. However, bear in mind that PWA support on iOS is very limited. Android has much better PWA support.
This article gives an overview of what is currently possible
I started developing a Bluetooth Low energy application on flutter with android studio ( Windows). As i heard flutter allows to create app for android as well as iOS, I'd like to install my app on an apple watch. But my research got me thinking that this feature was not available yet:
https://github.com/flutter/flutter/issues/2056
https://www.reddit.com/r/FlutterDev/comments/9fryg2/does_flutter_work_on_apple_watch/
So, as I need to develop this app for professionnal need and already coded my app on Flutter, I'd want to be sure that it's not possible or if some solutions exist.
We have created a Web App using material UI and React JS. It is working great and wanted to bundle it as a mobile app using Cordova.
The bundled Cordova Android app has been accepted on Google Play. However, the IOS version has been rejected by App store review team.
Reason given:
4.2 - Design
We continue to find your app provides a limited user experience as it is not sufficiently different from a mobile browsing experience. As such, the experience it provides is similar to the general experience of using Safari. It would be appropriate to include additional iOS interactive features within your app before resubmitting for review.
Has anyone managed to publish a react web app as an IOS app. What advice would you give us?
I am planing to develop an VoIP iOS app and use Twilios SDK. I am making the choice to either use LiveCode, Appery.io, PhoneGap or build a native Objective C app. I am going to build the app for iOS, Android and HTML5 so the ideal would be to develope in JavaScript for all platforms, but as I understand the support for WebRTC is laking on the iPhone so the alternative for iOS is the native twilio SDK.
My requirements is:
be possilbe to use in iPhone 5 with iOS 7 be able to use twilio iOS
SDK´s voip functionality or twilio´s js SDK (if it is possible to
wrap a browser that supports RTC in the code?) be able to integrate
billing such as in-app payment or paypal with zooz or similar
communicate with REST API´s such as Amazon S3 or a node.js server
store temporary info in a SQLLite db when app is off line make fast
and responsive views (file listings etc) is very important
create cfuuid´s
I have seen several Twilio projects that use PhoneGap but none that are using LiveCode.
I have already built an iOS VoIP app in Objective C, but I want to be able to release it on several platforms also such as for Android and build a HTML5 app, without redoing everything.
This isn't really a programming question and should perhaps not be asked here.
You can create an external for LiveCode and quickly create an interface using the LiveCode IDE. This is probably a quick and easy way to make a working app. If you're starting with LiveCode but are experienced in Objective-C, creating an external won't be a problem for you.
LiveCode doesn't contain native iOS controls, which means that you have to emulate the GUI. If you use PhoneGap, you also will need to compile a plugin for PhoneGap using Objective-C, but you can use a framework, such as JQuery, to get the right GUI.
Either way, you will have to compile the SDK and you'll need to be quite profound in Objective-C.
LiveCode will meet all your requirements. However, Apple will deny your app if you use PayPal for in-app purchases. You'll have to use Apple's in-app purchasing feature. I believe this is possible in LiveCode now. I'm not sure how easy it is.
I'm not sure about file listings either. On iOS, you won't have complete access to all files on the phone. This isn't a LiveCode limation but a limitation of the OS.
My team has developed a big social networking app. Now i want to publish it to app store. But the app is not written in Objective C. What is the way to get it published in app store? Or least how can i open in in Xcode simulator for testing and enhancement?
My guess is that you created an app in android and now want to port it to iOS. Unfortunately Xcode isn't able to transform Java to Objective-C and iOS cannot run Java apps, so you will not be able yo submit your app as-is to the App Store.
You will have to do it the hard way and rewrite the entire app in Objective-C. Luckily Google recently launched a translator that might help with part of the work: http://google-opensource.blogspot.com.br/2012/09/j2objc-java-to-ios-objective-c.html
You cannot. Sorry.
I recently worked on an app for iOS and Android launch and we settled for parallel development.
Your Java code is incompatible with iOS and Xcode has no process to convert it to Obj-c.
The only options for cross-platform development that I am aware of are:
1) Heavy use of c/c++ based libraries; these can be utilised in both Android applications and iOS applications (this is what we used). But the entire front end of the apps must be re-implemented.
2) A cross-platform framework such as PhoneGap or Appcelerator, but this would require significant redevelopment from your current code-base.
3) A 'translator' such as the one Breno Gazzola suggested (another option is XMLVM) but these only do some of the work for you, and they're far from perfect.
It's very hard to judge without knowing your code, but if I were you I'd look at combining options 1 and 3 as much as possible, but budget for a complete re-write.
